Gimp is an open source image editing program. "Adding gimp" was meant as a joke.

Methinks you've found a joke. GiMp = GNU Image Manipulation Program. 
Edit: Also beaten!

It's a joke. Gimp is a tool similar to Photoshop: http://www.gimp.org
Woelen has used the color manipulation tools to turn a picture of brown-red nitrogen dioxide gas into other colors of his choice.
